The Night after tomorrow – Sue Welford

When Jess’s boyfriend is killed in an accident, Jess thinks her life is over. But when she goes to stay with her aunt in the country, she meets an odd, wild boy in the forest and finds herself strangely attracted to him – but why is he so interested in the mysterious beast that has been killing local livestock? Why has no one ever seen his mother, and what is it that can only be done `the night after tomorrow’?
